Re: Neutralizing Silver Nitrate

My old Chief (now retired) remembers the balance of payments nightmare in the
60's when (apparently) UK labs were forbidden to throw away gold chloride
solution because we couldn't import the gold to make any more. They used to
recover the metal from the solution with zinc. I tried it the 70's and it
works (needs a lot of gold solution though). It is perhaps the only way we're
going to get rich in our profession!
